[0020] In order to further explain the technical solution of the present utility model, it will be elaborated in detail through specific embodiments below.

[0021] Please refer to Figures 1-3 , the present utility model provides a sealing structure for a syringe seat, including a syringe seat 1, and further including an installation groove 2 provided at the outer top end of the syringe seat 1. A set of bolts 3 are provided inside the installation groove 2, and a plugging mechanism 4 is provided at the bottom end of the bolts 3;

[0022] Among them, a set of concave rings 21 are provided in the middle of the installation groove 2, a set of stirring layers 22 are provided inside the concave rings 21, the inner side surface of the stirring layer 22 can contact the outer side of the bolt 3, and the bolt 3 is used to stir and break it. The cross-section of the concave ring 21 is in a quasi-spindle shape, gradually becoming smaller at the upper and lower ends. The damaged stirring layer 22 can rotate and move along with the bolt 3 and accumulate at the top end of the concave ring 21 for auxiliary sealing. Moreover, sealant is provided inside the stirring layer 22, and the sealant can flow out after the inner side of the stirring layer 22 is damaged. After it solidifies, the sealing effect can be improved.

[0023] Please refer to Figures 2-4, the present utility model provides a sealing structure for a syringe base. The plugging mechanism 4 includes an installation cylinder 41, a sealing member 42, a washer 43 and a fastener 44. A set of installation cylinders 41 are provided at positions of the syringe base 1 close to the bottom end of the installation groove 2. The inner side of the installation cylinder 41 is provided with internal threads. A set of sealing members 42 are provided at positions corresponding to the installation groove 2 at the inner top end of the installation cylinder 41. The sealing member 42 has ductility and elasticity, and a set of washers 43 are provided at the bottom end of the sealing member 42. The bolt 3 sequentially passes through the washer 43 and the sealing member 42 and then extends into the installation groove 2. The washer 43 can extrude the sealing member 42 through the movement of the bolt 3, so that it can fill the gap between the installation groove 2 and the bolt 3 to achieve a sealing effect. And a set of fasteners 44 are provided at the inner bottom end of the installation cylinder 41. The outer side of the fastener 44 is provided with external threads and can be connected to the installation cylinder 41. Among them, the direction of the external threads of the fastener 44 is opposite to the thread direction of the bolt 3, which can prevent the bolt 3 from sliding down due to loosening and maintain the sealing effect.

[0024] The working principle is as follows:

[0025] During use, the bolt 3 can be sequentially passed through the washer 43 and the sealing member 42 and then extended into the installation groove 2. When the bolt 3 rotates and moves upward in the installation groove 2, it can agitate and break the inner side of the agitation layer 22, accumulate the fragments at the inner top end of the concave ring 21, and can be assisted in sealing by the sealant in the agitation layer 22 to improve the sealing effect;

[0026] When the bolt 3 rotates to the end, its bottom end can extrude the sealing member 42 through the washer 43, so that the sealing member 42 fills the gap between the bottom end of the installation groove 2 and the bolt 3 to achieve a sealing effect. Finally, the fastener 44 can be rotated and fixed to the installation cylinder 41 to support the bolt 3 and prevent it from loosening.

[0027] The above are only the preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
